Look at this example
\relative c' {
\clef "alto" d'2 \tweak positions #'(8 . 4) ~
\clef "treble" d2
}
The `\tweak positions` doesn't work – which is kind-of expected.
However, for this very situation it would be nice if I could change
the start and end position of the slur manually.
Is there a way to do it, except faking the tie with a slur?
